He felt as though the memory of it was eating him from inside.

He felt as though the memory of it was eating him from inside. He had been so sure his parents were wonderful people that he had never had the slightest difficulty in disbelieving the aspersions Snape cast on his father's character. Hadn't people like Hagrid and Sirius told Harry how wonderful his father had been? (Yeah, well, look what Sirius was like himself, said a nagging voice inside Harry's head ... he was as bad, wasn't he?) Yes, he had once overheard Professor McGonagall saying that his father and Sirius had been troublemakers at school, but she had described them as forerunners of the Weasley twins, and Harry could not imagine Fred and George dangling someone upside-down for the fun of it ... not unless they really loathed them ... perhaps Malfoy or somebody who really deserved it .

Harry tried to make a case for Snape having deserved what he had suffered at James's hands: but hadn't Lily asked, ‘What's he done to you?’ And hadn't James replied, ‘It's more the fact that he exists, if you know what I mean.’ Hadn't James started it all simply because Sirius had said he was bored? Harry remembered Lupin saying back in Grimmauld Place that Dumbledore had made him prefect in the hope that he would be able to exercise some control over James and Sirius ... but in the Pensieve, he had sat there and let it all happen ...

Harry kept reminding himself that Lily had intervened; his mother had been decent. Yet, the memory of the look on her face as she had shouted at James disturbed him quite as much as anything else; she had clearly loathed James, and Harry simply could not understand how they could have ended up married. Once or twice he even wondered whether James had forced her into it ...

For nearly five years the thought of his father had been a source of comfort, of inspiration. Whenever someone had told him he was like James, he had glowed with pride inside. And now ... now he felt cold and miserable at the thought of him.

The weather grew breezier, brighter and warmer as the Easter holidays passed, but Harry, along with the rest of the fifth- and seventh-years, was trapped inside, revising, traipsing back and forth to the library. Harry pretended his bad mood had no other cause but the approaching exams, and as his fellow Gryffindors were sick of studying themselves, his excuse went unchallenged.

‘Harry, I'm talking to you, can you hear me?’

‘Huh?’

He looked round. Ginny Weasley, looking very windswept, had joined him at the library table where he had been sitting alone. It was late on Sunday evening: Hermione had gone back to Gryffindor Tower to revise Ancient Runes, and Ron had Quidditch practice.

‘Oh, hi,’ said Harry, pulling his books towards him. ‘How come you're not at practice?’

‘It's over,’ said Ginny. ‘Ron had to take Jack Sloper up to the hospital wing.’

‘Why?’

‘Well, we're not sure, but we think he knocked himself out with his own bat.’ She sighed heavily. ‘Anyway ... a package just arrived, it's only just got through Umbridge's new screening process.’

She hoisted a box wrapped in brown paper on to the table; it had clearly been unwrapped and carelessly re-wrapped. There was a scribbled note across it in red ink, reading: Inspected and Passed by the Hogwarts High Inquisitor.

‘It's Easter eggs from Mum,’ said Ginny. ‘There's one for you ... there you go.’

She handed him a handsome chocolate egg decorated with small, iced Snitches and, according to the packaging, containing a bag of Fizzing Whizzbees. Harry looked at it for a moment, then, to his horror, felt a lump rise in his throat.

‘Are you OK, Harry?’ Ginny asked quietly.

‘Yeah, I'm fine,’ said Harry gruffly. The lump in his throat was painful. He did not understand why an Easter egg should have made him feel like this.

‘You seem really down lately,’ Ginny persisted. ‘You know, I'm sure if you just talked to Cho ...’

‘It's not Cho I want to talk to,’ said Harry brusquely.

‘Who is it, then?’ asked Ginny, watching him closely.

‘I ...’

He glanced around to make quite sure nobody was listening. Madam Pince was several shelves away, stamping out a pile cf books for a frantic-looking Hannah Abbott.

‘I wish I could talk to Sirius,’ he muttered. ‘But I know I can't.’
